One more option, not a mandate Three ways it grows here 1 2 3 Mac switchers Companies Outside Tokyo Japanese web devs are unusually Mac-heavy. Omarchy M installs beside macOS on Apple Silicon. No new PC needed. 37signals moved its whole technical team. In Japan: zero so far. But OPTiM, ANDPAD and KOMOJU already host us. Dozens of meetups worldwide this month: Seoul, Taipei, Shenzhen. Japan has only Tokyo. Osaka, Fukuoka, Sapporo, Matsue are open.
What's missing, and what Japan gave back Today 18:13 JST · dhh + AI · "Omarchy in 50 languages" (#15326) · 2,909 files · Japanese included Empty seats Japanese UI and manual strings: plain JSON in default/i18n/ja/, hours old, untouched Omacom Foundation patrons from Japan: 0 Core team members from Japan: 0 Bugs only Japan could find 全・骨・円 rendered with Korean glyphs (#9580) Ctrl + "+" never zooms on a JIS keyboard (jis.lua) Invisible on DHH's keyboard, in DHH's language. Found because Japanese people used it. Fixed last week. With AI, "I can't code" is no longer a reason. None of these seats needs permission. The more diverse the users, the better Omarchy gets. That is not a slogan; it is the commit log.

What I'll do 10 USB sticks of Omarchy, handed out at Kaigi on Rails Oct 16–17, Shibuya. Plug it into a spare PC, pick "Japanese" in the installer. Then come to the next Omarchy Tokyo Meetup and tell me how it went. No strings. Keep the stick.
omarchy.jp 「Omaはおまかせ、 シェフのおまかせってこと」 "Oma is for omakase — chef's choice." In Japanese, the pun needs a footnote. Omakase is an everyday word here: just make it good. Start with omakase. Change it with the AI. Tell a friend. Omarchy is one option. The people who grow it type on different keyboards, in different languages.
